Praxis M30 386EVO Bottom Bracket

The Praxis M30 386EVO Bottom Bracket is a 386EVO bottom bracket designed for Praxis M30 spindles. The M30 spindle has a tapered 30 mm drive side and 28 mm non-drive side diameter. This bottom bracket is available with steel or ceramic bearings and uses machined heat-treated aluminum cups. It is made for frames that can accept a 386EVO bottom bracket, meaning the bottom bracket cups are pressed into the frame.
